SIOUX FALLS, S.D. (AP) -- American Indian radio stations have a new partner helping them broadcast an eclectic mix of community programming to reservations across the country.

The Center for Native American Radio offers 33 radio stations that serve Indians help with programming, accounting, engineering and fundraising, which is a big challenge for most of the noncommercial operations.

A $1.5 million grant from the Corporation for Public Broadcasting established the center, which is overseen by the National Federation of Community Broadcasters in Oakland, Calif.

America's 4.2 million Indians often live on reservations located far from each other, increasing the sense of isolation for some of the nation's poorest, most vulnerable groups. Radio stations that cater to their interests could help boost morale, provide networking opportunities and give them a sense that they aren't alone, proponents say.

''We're now this unified group. Before, the stations were sort of on their own and a lot of them felt isolated,'' said Peggy Berryhill, director of services and planning.

''So now they're beginning to see their collective strengths and share their assets and issues and begin moving forward.''

The center doesn't provide funding, but it connects stations with people and groups who know how to find money that's available, she said.

Berryhill said strengthening Indian radio stations helps Indian communities maintain their traditions and sovereignty.

''The mission of most of these stations is about cultural preservation,'' she said. ''It's about economic development for the reservation. It's about having a voice for their communities, an independent media.''
